Things to consider before selecting an air cleaner?
———————————————————————————————————————- How do I know which air cleaners are really effective? The Clean Air Delivery Rate (CADR) is the standard by which portable room air cleaners are evaluated. You will generally see CADRs expressed for the three most common types of pollutants: TOBACCO SMOKE, DUST and POLLEN. CADR refers to the amount of clean air provided by an air cleaner each minute of operation – measured in cubic feet. ^ TOP ———————————————————————————————————————- Why measure efficiency at 0.3 micron? Media air cleaners are rated accordingly to their ability to capture particles 0.3 microns in size. Why? Because these particles are the most difficult to remove from the air. In standard tests using dioctyl phthalate (D.O.P.) which generates 0.3 micron particles when tested, Honeywell hospital grade filters were rated at 95
